Due to the nature of web engine workloads migrating objects to being GC'd isn't performance negative (as most people would expect). With care it can often end up performance positive.
There are a few tricks that Oilpan can apply. Concurrent tracing helps a lot (e.g. instead of incrementing/decrementing refs, you can trace on a different thread), in addition when destructing objects, the destructors typically become trivial meaning the object can just be dropped from memory. Both these free up main thread time. (The tradeoff with concurrent tracing is that you need atomic barriers when assigning pointers which needs care).
This is on top of the safey improvements you gain from being GC'd vs. smart pointers, etc.
One major tradeoff that UAF bugs become more difficult to fix, as you are just accessing objects which "should" be dead.

Project mention: This year in Servo: over 1000 pull requests and beyond | news.ycombinator.com | 2023-12-18
I thought it would be a fun weird project to make Servo work with MS' abandoned JavaScript engine:
https://github.com/chakra-core/ChakraCore
Of course it is written in C++ and you'd probably want a pure Rust browser. But it is sad seeing that fairly complete open source JIT JavaScript engine sit and rot.

For debugging elements kinds to figure out a given object’s “elements kind”, get a debug build of v8 (either by building from source in debug mode or by grabbing a precompiled binary using jsvu), and run: out/x64.debug/d8 --allow-natives-syntax Note that “COW” stands for copy-on-write, which is yet another internal optimization. :))
